Taken from MajorGeeks:
Auslogics BoostSpeed 5 Special Edition will enhance your PCs performance with a host of useful optimisation tools.
The Disk Cleaner, for instance, will search your hard drive for junk files that can safely be deleted.
The Registry Cleaner wipes away redundant Registry entries, then Auslogics Disk Defrag reorganises your files to improve Windows and application speeds.
The bundled Startup Manager displays everything that's launched when Windows starts, as well as Internet Explorer addons and Explorer extensions. Potentially dangerous programs, like spyware, are highlighted, so they're easy to remove. And anything else you decide you don't need can be disabled at a click, improving boot time and freeing up valuable system resources.
BoostSpeed 5's System Advisor then scans your system for configuration issues, and recommends possible changes: Windows services that can be safely disabled, security tweaks you should make, and so on.
And if you're in a hurry and don't have time to explore all these tools, then you can always leave BoostSpeed 5's System Scan to do the hard work for you. In a couple of click it will start scanning your PC for Registry issues, junk files, unwanted internet and application histories, fragmented hard drives and more.
The System Scan will then automatically repair any issues it finds, and can even shut down your PC when it's done, the perfect solution for unattended, hassle-free PC optimisation.
In short, Auslogics BoostSpeed 5 SE Version is a crippled version of Auslogics BoostSpeed 5.
